Import Automatic Transmission Diagnostics

Don’t be alarmed if you pull an automatic transmission trouble code when diagnosing a “check engine” warning light! Since the automatic transmission operation has a major effect on grams-per-mile exhaust emissions, you’re going to see the occasional “global” P0700 to P0900-series diagnostic trouble codes (DTCs). The fact is, if you understand basic transmission operating principles,

Perform Transmission Fluid Service By ‘Severe Duty’ Change Interval

Improved lubricants have allowed service intervals to extend for many vehicles with automatic transmissions, utilizing “lifetime fluids.” Lifetime fluid recommendations are now 5-10 years or the life of the vehicle (100,000 miles) unless the vehicle is subjected to “severe duty.”

Inspect The Automatic Transmission Filter And Fluid

Changing the automatic transmission filter and fluid is a great preventive maintenance practice, ensuring a clean and proper working transmission assembly. The most important factors are installing the correct filter for the vehicle application and the correct installation procedures of the filter. An incorrect filter installation or the wrong filter will ultimately cause erratic shifts and possibly cause damage to the transmission assembly.

Three Causes Of Transmission Complaints

The modern transmission is one of the most connected components on a vehicle. When using a scan tool to diagnosis a drivetrain problem, it’s often what is not displayed on the scan tool that will lead you to your final diagnosis. Read on for three of the common causes of transmission complaints.

Start Solving Transmission Electronic Control Problems

Troubleshooting an automatic transmission can be one of the most intimidating diagnostic procedures at a shop. The first reaction is typically, “We don’t do that type of work.” But there is profit in performing drivetrain diagnostics and “in-the-car” repairs.

Automatic Transmission Erratic Shifts After Filter Replacement

Changing the automatic transmission filter and fluid is a great preventive maintenance practice, ensuring a clean and proper working transmission assembly. The most important factors are installing the correct filter for the vehicle application and the correct installation procedures of the filter. An incorrect filter installation or the wrong filter will ultimately cause erratic shifts and possibly cause damage to the transmission assembly.

ASE A2 Test Prep (Automatic Transmission/Transaxle Test Prep): Torque Converter Basics

The concept of using a torque converter, oil pump, planetary gear sets, clutches, bands and a computer-controlled hydraulic valve body to transmit torque and to change gear ratios is relatively simple.

Tech Tip: Dodge Has A P2767 Code With Transmission In Limp In Mode

If you encounter a Dodge with a P2767 trouble code set, check the wiring between the transmission and the transmission control module. Make sure the #2 signal wire is not open, shorted to ground, or shorted to any other circuit. If the wiring checks OK, raise all four wheels off the ground, start the vehicle and place the shifter in drive. While lab scope testing the #2 signal wire, obtain second gear. When the transmission is in second gear, there should be a 5-volt square wave pattern being produced by the #2 sensor. If not, replace the sensor.
